Bleeding
Description
Color inks, printed side by side, mix together at the border. Also occurs at areaĆfill borders
with a high color saturation.
Causes
The ink is not properly absorbed by the media and spreads from its original position. Media
types affected are bonds.
Corrective Actions
Plot in an interlaced print mode (Best), thus increasing the number of passes over the media.
Set the lightness to lighter" to reduce the amount of ink used.
Feathering
Description
Ink spreads along the media fibers, affecting the edge roughness of the lines and text.
Causes
The medias does not control the dot growth. The affected media types are:
D Bonds.
D Natural tracing paper.
D Vellum.
D Translucent bond.
Some third party media types have unacceptable results.
Too large a drop volume increases the severity of the problem.
Corrective Actions
Plot in an interlaced print mode (Best), thus increasing the number of passes over the media.
Set the lightness to lighter" to reduce the amount of ink used. Use HP media.
Migration (Black)
Description
In area fills, ink accumulates in the external part of the swath, where the black is more
saturated.
Causes
Ink not properly absorbed by the media, and surface forces, push the black ink to the borders
(due to the chemistry of the black ink). All the CAD media types except coated paper are
affected.
